ChromeOS-Administrator - Professional ChromeOS Administrator Exam

Single sign-on (SSO): This allows users to sign in to their Chrome OS device using their organizational credentials. This is particularly useful in enterprise or educational settings where users already have an existing account.

Facebook Connect: This allows users to sign in to their Chrome OS device using their Facebook credentials. This can be convenient for users who are already logged into Facebook on another device.

Options A and C are incorrect:

SMS code sent to mobile phone: This is not a standard sign-in method for Chrome OS devices.

Google Friend Connect: This was a social networking service that has been discontinued.

Option D is the most proactive and comprehensive approach to ensure application compatibility with new Chrome versions. Here's why:

QA Strategy: Implementing a formal Quality Assurance (QA) process allows for systematic testing of applications on new Chrome versions before they are released to all users. This helps identify and address compatibility issues early on.

Beta Channel Testing: Enrolling a subset of users (e.g., IT group and 5% of users) in the beta channel gives them access to pre-release versions of ChromeOS. This allows them to test applications in a real-world environment and report any bugs or issues before the stable release.

Early Bug Reporting: By identifying and reporting bugs early, you provide developers with valuable feedback and time to fix issues before the official release. This ensures a smoother transition for all users when the new Chrome version is deployed.

Why other options are incorrect:

A: User feedback is valuable, but it's reactive and may not catch all issues before they impact a larger user base.

B: Assuming all applications are automatically compatible is risky and can lead to unexpected problems.

C: While keeping applications updated is good practice, it doesn't guarantee compatibility with new Chrome versions, as changes in Chrome itself can cause issues.

Device State: Before you can enroll a ChromeOS device into an enterprise environment, it's crucial that it's not associated with any personal Google accounts. Existing consumer accounts can interfere with the enrollment process and the application of enterprise policies.

Data Backup (Optional): If the existing consumer accounts on the device contain important data, advise the users to back up their information before proceeding.

Account Removal: Sign in to the device with each consumer account and remove the account from the device. This ensures a clean slate for the enterprise enrollment process.

Powerwash (Optional): While not strictly necessary after removing accounts, performing a powerwash (factory reset) is a recommended step. It further erases any remaining data or configurations linked to the consumer accounts, ensuring a completely fresh start for the device.

Enrollment: Once the consumer accounts are removed (and optionally, after powerwashing), follow the standard enterprise enrollment steps for your organization. This typically involves entering enterprise credentials at the login screen, or using a unique enrollment token, depending on your company's setup.
